    Happy New Year Everyone, Im new to this so I apologize if Im not in the right place. I drive a 94 T800 dumptruck with a 3406b 3zj. Our mechanic doesnt seem to wanna run the overhead or get involved in it. Can anyone tell me where to find a rebuild kit for the jakes? I believe they are 346d. And injectors. The pump was turned up by Cat about 10yrs ago idk if that matters. Or a place I can take it too, We are located on Long Island. Thanks in sdvance

    For the jake tune up kit, you will need Cat pn#143-6479. On the 3406b and c, injectors are called nozzles. The nozzles stock replacement are Cat pn#100-7556, also ask them for the o-ring kit and carbon dam seal kit for the nozzles.

    As for a shop to take it to, you could try Gabrielli Kenworth in Hicksville or Hunter Peterbilt in Kutztown, PA or Swedesboro, NJ, or there is a kenworth dealer in Swedesboro, too. Any of these locations can get these cat parts for you.
